v lfll/f PAIENTED H 1 1 #914 3815; 17 4 SHEET 2 OF 2 For displaceably suspending drapes and curtains, it is known to provide profiled rails which are connectable to the ceiling or the wall by means of suitable holding means and which are extrusion pressed from synthetic material. Bymeans of slides or suspension members adapted to slide on the profiled rails, the drapes or curtains are suspended. To this end, the drapes or curtains have their upper edge provided with a suitable suspension binding to which at certain equal distances the suspension members or slides are connected directly or through intermediate members.

In this connection it is likewise known to provide the suspension members'or slides with a slide head which, when viewed in profile, has a multi-cornered hook shape. It is also known so to design the rail profile that the slides can be suspended therein anywhere while the angled-off end of the slide head extends around the inner longitudinal edge of a sliding strip of the rail so that, when the drapes or curtains swing back and forth, the slides will be held fast on the slide rail. With a hard and smooth surface of the profiled rail and the slides and with only a minor edge contact therebetween, a very low frictional resistance is encountered.

It is an object of the present invention so to further develop and improve an outer runner profiled rail and the pertaining slides that the sliding resistance between the profiled rail and the slides will be further reduced while the safety of the slides against jumping out of the rail when the drapes or curtains swing back and forth will be further considerably increased and the slides will not get stuck at the joints of profiled rails and on curved sections of the rails without affecting the easy handling of the slides.

This object and other objects and advantages of the invention will appear more clearly from the following specification in connection with the accompanying drawings, in which:

FIG. 1 shows a cross section through a profiled rail according to, the invention with a pertaining slide.

FIG. 2 is an end view of the rail of FIG. I with a pertaining slide.

FIG. 2a is a top view of a drape or curtain pleating device which is adapted to be connected to the slide at different heights.

FIG. 3 illustrates a section through a double-profile rail according to the invention for two drapes or curtains.

FIG. 4 is an isometric view of a reinforcing body intended for the profiled rail of FIG. 3.

FIG. 5 is a section through a profiled rail similar to that of FIG. 3.

FIG. 6 is a section and side view respectively of a profiled rail and slide similar to that of FIGS. 1 and 2.

FIG. 7 illustrates in section and side view a modification of the profiled rail and slide of FIG. 6.

FIG. 8 illustrates similar to FIGS. 6 and 7 a further modification of the profiled rail and slide of the invention.

FIG. 9 illustrates in section and side view respectively I approximately perpendicularly with regard to the axis of the slide bar. The head has a crowned surface by means of which it slidably rests on a plane horizontal surface section of the profiled rail. The device according to the invention is furthermore characterized in that the profiled rail has at least one special guiding strip or section which is independent of the' plane horizontal surface section and which is so arranged with regard to the latter that the slides can freely pendulate on the plane horizontal surface section and can only in a position which greatly differs from-their position of use be introduced into and removed from the profiled rail.

Due to the fact that the slides by means of a crowned surface rest freely pendulating on the top side of the plane horizontal surface section, a very low sliding resistance is encountered when the profiled rail and the slides have a sufficiently hard and smooth surface because even in an inclined position of the slides there is actually only a point contact between the slides and the profiled rail. Consequently also at joints and curbed portions of the profiled rail the slides will not get stuck in the rail.

A jumping out of the slides from the profiled rail will be safely avoided due to the fact that the dimensions of the slides, especially of the slide heads, with regard to the position of the sliding strip and the guiding strip, i.e., the free width between the free edge of the sliding strip and the free edge of the guiding strip, are so selected that the slides are adapted to be introduced into or removed from the profiled rail only in a position in which they are tilted by approximately about their longitudinal axis with regard to their position of use or- /and by a greater angle about an axis which is parallel to the longitudinal axis of the profiled rail.

A particularly simple and reliable solution 'of the problem underlying the present invention is obtained for a profiled rail in which the plane horizontal slide strip is arranged by means of a vertical supporting strip on a ceiling flange provided for connection of the profiled rail to the ceiling when the additional guiding strip is provided on the supporting rail section or on the ceiling flange, especially at the outer edge thereof.

According to a particularly simple solution, the additional guiding'strip may be composed of a plane strip which is spaced-from the free edge of the sliding strip section and extends to a point below the level thereof.

According to another similar embodiment of the invention the additional guiding strip section may be composed of a guiding strip section which by means of a vertical supporting strip section is connected to the ceiling flange and extends above the sliding strip section toward the supporting strip section.

In the first mentioned instance no special guiding means are provided on the slides. In order to prevent the slides from getting stuck in the profiled rail, especially at joints and in curved portions, it will suffice to provide those areas of the slides which engage the profiled rail, especially the free edges of the sliding rail section and the edges or surfaces of the guiding rail section, with a spherical or crowned contacting surface.

When the guiding rail section is located above the sliding rail section, it is necessary to provide the slides. especially the heads thereof, with a separate guiding element which by means of a stay is connected to the slides, especially the slide heads. Also the surfaces of such guiding element which contact the guiding strip section should, in conformity with the present invention, be spherical or crowned to prevent the slide from getting stuck.

A further important feature of the invention consists in that the plane horizontal slide rail section or supporting rail section is provided'so as to form a component of a closed hollow profile whereby the profiled rail will obtain a particularly accurately dimensioned stable shape. If desired, also'the guiding rail sections may form a component of a closed hollow profiled part so that the profiled rails may be connected to curved sections which without major steps merge with the straight rail sections.

Referring now to the drawings in detail, the profiled rail illustrated in FIGS. 1 and 2 comprises the following rail sections: a closed rectangular rail section 1 which includes a ceiling flange 2, 2', two supporting strips 3 and 4 connected to the flange section 2 and a bottom strip 5 interconnecting the lower ends of the supporting strips 3 and 4. The rail section 1 is intended'for connecting the profiled rail in any convenient manner to the ceiling or to a wall. The rectangular rail section 1 has connected to the lower portion of its supporting strip 3 a likewise closed profiled section 6 of trapezoidal cross section. This section 6 comprises a horizontal plane sliding strip 7, a supporting strip 8 extending downwardly from the outer edge of strip 7, and a bracing strip 9 connecting the lower end of the supporting strip 8 with the lower end of the supporting strip 3. That portion 2' of the ceiling flange 2, 2' which is located outside the rectangular rail section 1 has its outer edge provided with a downwardly extending supporting strip 10 the lower end of which has connected thereto a guiding strip 11 extending in the direction toward the supporting strip 3. A profiled rail of this construction is highly shape, retaining and can be produced of synthetic material by extrusion pressing with a smooth surface. The functionally most important parts of the rail according to the invention arethe horizontal sliding strip 7 which is plane and is provided with a very smooth and hard surface for the support of the slides, and the guiding strip 11 which is connected to the ceiling flange 2, 2 and serves for guiding the slides.

The slide generally designated with the reference numeral l2 and likewise made of a hard and smooth synthetic material comprises a straight flat slide rod or bar 13 for suspension of the drapes or curtains. With the specific illustrated embodiment of the slide, the slide rod 13 has its flat front side provided with round extensions 14. There is furthermore provided a counter member 13 corresponding to the rod 13 with the extensions 14; the counter member 13' is provided with bores 14 for receiving the extensions 14. The suspending means proper for the drapes or curtains, for instance a transverse strip with pleating bars 15, are connected to the bar 13'. Devices of this type are known and, therefore, no further explanation thereof appears to be necessary. In this connection it is, however, important that the suspension means l3, l4 and 15' which are to be connected to the slide rod l3, 14 can be connected thereto at different heights, i.e., in the specific embodiment shown, at three different heights whereby it is possible in a simple manner to suspend the drapes or curtains at three different levels. The slide rod 13 is furthermore above the uppermost extension 14 provided with a round or cornered bore 16 adapted to arrest the slide on the profiled rail.

Connected to the slide rod 13 and extending in upward direction is a curved neck 17 which ends in the slide head 18. By means of the slide head 18 the slide rests on the top side of the slide rail section 7. The slide head 18 has a crowned or spherical bottom side 19 so that its contact surface with the slide surface will approximately be a point contact even when the slide occupies a more or less inclined position. In view of this shape of the slide surfaces contacting each other, the frictional resistance is extremely low, and it will be assured that the slide cannot get stuck on joints in the profiled rail. The neck 17 is likewise provided with a crowned or spherical engaging or contacting surface 20 by means of which the slideengages the outer surface of the vertical supporting strip 8.

The slide head l8, 19 has connected thereto a bracing member or extension 21 which extends upwardly in the direction toward the supporting strip 3. The extension 21 ends in a hook-shaped member 22 which reaches or extends over the guiding strip 1 l. The member 22 should be located above the guiding strip 11 in slightly spaced relationship thereto. The member 22 actually has no supporting function but its purpose consists in preventing the slide from slipping out of the rail,

especially when the drapes or curtains swing back and forth. The surfaces 23 and 24 facing the slide are likewise crowned or spherical so that also in this instance the slide cannot get stuck on the joints of the profiled rail.

The shape of the guiding means comprising the ceiling flange portion 2, the supporting strip 10 and the guiding strip 11 may vary and may be, for instance, of arcuate or semicircular cross section. Also the guiding member 22 may have a different shape, for instance, a ball shape. It is merely important in this connection that the slide during a swinging back and forth of the curtains is freely movable with considerable play in the hollow space above the sliding strip 7 while being prevented from sliding out of the profiled rail. To be able to remove the slide from or to insert the slide into the profiled rail, the slide has to be tilted by a considerable angle about an axis which is substantially parallel to the longitudinal axis of the rail and extends approximately through the center of the slide. In the specificshowing of FIG. l,-the slide will for this purpose have to be tilted in counterclockwise direction. Individually the slides can also be easily introduced into and removed from the profiled rail by turning the slides by approximately about their central axes.

FIG. 3 shows an embodiment of the invention for two drapes or curtains with an image-symmetric design of the profiled rail shown in FIG. 1. All parts of FIG. 3 which correspond to those of FIG. I are designated with the same reference numerals. To be able to mount this rail in a simple manner, for instance by pegs, studs, screws, or the like, to the ceiling, the rail section I of FIG. 1 which is closed has been replaced by a section 1' which is open at the bottom side and in which those surfaces of the supporting strips 3 which face each other are approximately at the level of the sliding strips 7 provided with angular strips 25 the free legs of which point upwardly. On the inner side of one supporting strip 3, near the lowe edge thereof, there is provided a further angular strip 26 the free leg of which point downwardly. Opposite the leg 26 and connected to the bottom end of the other supporting strip 3 at a section 27 reduced in cross section there is provided a cover strip 28 with a closure strip 29 at the free edge of strip 28. From the end 'of the rail, above the angular strips 25, reinforcing bodies 30 may be inserted and arranged in spaced relationship to each other. These bodies 30 have their lower longitudinal edges provided with two strip-like legs 31 which catch the free legs of the angular strips 25. The reinforcing bodies 30 may at their central portion in vertical direction be provided with a hole 32 to which corresponds a hole 33 in the center of the ceiling flange portion 2. In this way a connecting screw may be passed therethrough from below. After the profiled rail has been mounted, the cover strip 28 with its closure strip 29 can be pressed into the opening 34 between the left-hand supporting strip 3 and the angular strip 26 so that the profiled rail will have its bottom side completely closed. However, if desired, at both sides of the supporting strips 3 there may be provided angular strips 26 in which instance the lower opening in the profiled rail may be closed by a separate cover strip.

FIG. 5 shows an embodiment similar to that of FIG. 3 in which, however, the profile of the rail is somewhat lower or wider. The rail section which comprises the sliding strip 7 is in this instance additionally provided with a lower horizontal bracing strip 34 and a diagonal strip 35 on each side of the rail.

The embodiments illustrated in FIGS. 6 to 9 show different configurations of the profiled rail and of the slide according to the invention. Also with these embodiments the slides are adapted to be introduced into and removed from the profiled rail when occupying a tilted or turned position which greatly differs from the position of use. With the embodiments illustrated in FIGS. 6 to 8, for increasing the rigidity of the profiled rail, there is provided a further supporting strip 37, 37 This strip 37, 37' extends from an upper or central connection 36, 36at an incline to the vertical supporting strip 3 and extends to approximately the central portion of the sliding strip 7 The free end of the sliding strip 7 has connected thereto a short supporting strip 8'.

According to the embodiment of FIG. 6, adjacent the vertical supporting strip there is provided a guiding strip Ila which extends at an incline inwardly and upwardly. In conformity with the shape and position of this strip 11a the upper edge of strip 1 la is partially surrounded by a somewhat more curved guiding member 22a which also in this instance is connected to the head 18 of slide 12 by a brace 21. The not specifically designated contacting surfaces of the slide with the profiled rail are also in this instance crowned or spherical. The

safety of the slide against accidental slipping out of the.

rail is in this instance even greater than with the embodiment of FIGS. I and 2, while the insertion and removal of the slide is likewise possible only when the slide is pivoted away from its position of use by approximately 45 in counterclockwise direction or in this pivoted position is simultaneously turned about its longitudinal axis by an angle of 90.

With the embodiment of FIG. 7, adjacent the junction 36' slightly below the ceiling flange 2, 2' at the inner side of the supporting strip there is provided a guiding strip 11b which extends at an incline in upward direction while the guiding member 22b extends about its upper edge. The introduction and removal of the slide into and out of the profiled rail is possible in this instance only when the slide is tilted from its position of use in counterclockwise direction by about 45 while it is simultaneously turned about its longitudinal axis by an angle of 90. With this embodiment the width of the slide must not be greater than the free opening a between the ceiling flange member 2' and the upper edge of the guiding strip 11b. The slide may otherwise be designed in the same manner as the slide described in FIGS. 1, 2 and 6.

With the embodiment of FIG. 8, the free edge of the sliding strip 7' has connected thereto a guiding strip 110 which extends vertically in upward direction while a confining strip 39 extends from the free edge of the ceiling flange 2' in downward direction, the strip 39 being located in approximately the same plane as the guiding strip 11c. Between the two strips 110 and 39 there is thus created a gap having a width b. The slide 12 has a somewhat eye-shaped head 18a which has its arched or spherical lower end 19' resting on the sliding strip 7'. The width of the slide should also in this instance not exceed the width b of the gap for the introduction of the slide. The introduction of the slide into and the removal'of the slide from the profiled rail is in this instance effected by tilting the slide either by 90 toward the longitudinal axis of the profiled rail or, in conformity with FIG. 8, in counterclockwise direction by an angle of 90 whereupon the slide is turned about its longitudinal axis by an angle of 90.

' With the embodiment of FIG. 9, the vertical supporting strip 3 has connected to the lower end thereof a relatively narrow sliding strip 7 beyond which slightly protrudes the ceiling flange portion 2' so that a gap 0 is formed. This gap c is due to the fact that from the free end of the ceiling flange portion 2 there extends a relatively wide guiding strip 11d up to a level below the level of the top side of the sliding strip 7 The slide 12 is in this instance provided with a head having the shape of a somewhat horizontally extending hook 18b while the width of the slide should expediently not be greater than the width of the gap c. The introduction into and the removal of the slide from the profiled rail may be effected either by tilting the slide about its vertical axis by or by tilting the slide about an axis parallel to the longitudinal axis of the profiled rail by approximately 45 and in the specific showing in FIG. 9 in clockwise direction. Also with this embodiment of the profiled rail and slide according to the invention the surfaces of the slide which contact the profiled rail should, similar to the embodiments described above, be crowned or spherical. The surfaces involved here are the surfaces designated with the reference numerals 19, 20 and 23'.

It may be added that while various materials are suitable for the profiled rail and the slide, it has been found highly satisfactory to make the profiled rail of polyvinylchloride (PVC) and to make the slide of an acetal copolymerisate sold under the trade name Hostaform by the company I-Ioechst in Germany.

It is, of course, to be understood that the present invention is, by no means, limited to the specific showing in the drawings but also comprises any modifications within the scope of the appended claims.
